CMR
Compact Measurement Record. This is an RTK
correction protocol.
DGPS
Differential Global Positioning Svstem, commonly
used as a term to describe a GPS position corrected
by a base station to remove some of the common
position errors.
EDGE
Enhanced Data rates for GSM Evolution. The EDGE
protocol allows improved data transmission rates, as
an extension of standard GSM. EDGE is a third-gener-
ation (3G) technology.
Ephemeris
A list of positions or locations of a celestial object as
a function of time.

GPS
GPS is the short form of NAVSTAR GPS, which stands
for NAVigation System with Time And Ranging
Global Positioning System.
HSDPA
High-Speed Downlink Packet Access. HSDPA is a
protocol for cell phone data transmission. It is
referred to as a 3.5G technology (G stands for Gener-
ation). The HSDPA protocol provides download
speeds on a cell phone that are equivalent to ADSL
(Asymmetric Digital Subscriber Line) downloads on a
landline. HSDPA evolved from, and is an improvement
on, the W-CDMA protocol (a 3G protocol).
Latitude
The angle between the ellipsoidal normal and the
equatorial plane. Latitude is zero on the equator and
90° at the poles.
Longitude
Longitude is the angle between the meridian ellipse
which passes through Greenwich and the meridian
ellipse containing the point in question. Thus, longi-
